he bar chart illustrates the proportion of households utilizing five distinct energy sources – Electricity, Gas, Coal, Solar, and Wind – in the years 2000 and 2020.
Overall, electricity and gas were the most predominant energy sources in both years, with both experiencing an upward trend over the 20-year period. Conversely, coal usage saw a significant decline, while renewable energy sources, specifically solar and wind, recorded notable increases.
In 2000, electricity was the most widely used energy source, accounting for 45% of households, followed closely by coal at 40% and gas at 35%. Renewable energy sources accounted for a minor fraction of overall usage, with solar energy used by only 5% of households and wind power by just 2%.
By 2020, reliance on cleaner and more modern energy options grew considerably. Electricity usage rose by 25 percentage points to reach a peak of 70%, maintaining its status as the leading energy provider. Similarly, gas usage increased to 50%, and solar energy experienced a sixfold rise to 30%. Wind energy also grew, reaching 18% of households. In contrast, coal consumption dropped sharply to 15%, shifting from one of the primary sources to one of the least utilized.
